Title: Portable terahertz frequency domain spectrometer with frequency shifting of source laser beam
Inventor: LOGAN RONALD T JR
IPC: G01J3/02
Filed: 2010-10-08
Abstract: A terahertz spectroscopy apparatus for analyzing, identifying or imaging a target is disclosed. The apparatus comprises a first portable housing 100 including tunable lasers 105, 106 coupled to first and second optical fibres 117, 118; a second housing 201 including photoconductive switch 204 activated by an optical beam from the first optical fibre 117 to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on and transmitted through or reflected from the target; and a third housing 202 including photoconductive switch 207 activated by an optical beam from the second optical fibre 118. A detector 209 acquires spectral information from signals received from the target and may use a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a frequency shifter 113 in the path of one laser beam may allow the terahertz beam to be finely adjusted in one or more selected frequency bands. Alternatively separate frequency shifters (450, 451, Fig 4) may be employed in both laser beam paths.

IPC: G06F9/315
Filed: 2007-03-12
Abstract: A data processing system has a select-and-insert instruction, which takes two input values. The instruction shifts the first valuenbits, selectsnbits from the second value and concatenates the shifted value with the selected bits to produce a result. If the first value is left shifted, then the selected bits form the least significant bits of the result. If the first value is right shifted, then the selected bits forth the most significant bits of the result. The instruction may be used in a Viterbi decoder with the first input being a Viterbi decoder state and the second value being a Viterbi trellis value.

Title: Control of a brushless motor
Inventor: CLOTHIER ANDREW CHARLTON
IPC: H02P6/00
Filed: 2011-03-29
Abstract: Control of a brushless permanent-magnet motor comprises rectifying an alternating voltage to provide a rectified voltage having a ripple of at least 50%, and exciting a winding of the motor with the rectified voltage. In response to current in the winding exceeding a threshold that is proportional to the rectified voltage the winding is either freewheeled or the excitation continues for an overrun period and then the winding is freewheeled. If the motor speed is below a threshold the winding can be excited and freewheeled repeatedly over each electrical half cycle of the motor but if the speed exceeds the threshold the winding can be excited, overrun and freewheeled only once per half-cycle. The overrun period can be adjusted depending on the motor speed or the RMS alternating voltage and can vary over each half-cycle of the alternating voltage, increasing over its first half and decreasing over the second half. The overrun period can comprise a components that is constant over a half cycle, adjusted in response to the speed or the RMS voltage and a component that varies as a half-sinusoid over the half-cycle, determined from the time since a zero-crossing of the alternating voltage. A phase offset can be applied to the measured current used to determine whether the winding current exceeds its threshold.

Title: Door handle sanitizer mechanism
Inventor: MATRAXIA ANGELO
IPC: A61L2/16
Filed: 2013-01-26
Abstract: A mechanism placed within the edge of a door and above a door handle 7 which depresses the cap on a capsule of sanitizer 2 which in turn sprays sanitizer 1 onto the door handle 7. There is a door press mechanism 5 which is pushed within a door jamb when the door is closed which causes the spray button push 4 to move onto the folded spray button push/release 8. This then depresses the spray cap of the sanitizer and sprays the door handle. When the door is fully closed, the spray button push 4 slides to the end of the button push/release mechanism 8 so as to not continuously depress the sanitizer spray cap. In another embodiment, the depression of the sanitizer cap is completed by a motor (14) which is activated by a switch (13) when the door is closed.

Title: Method for testing the integrity of electronic equipment
Inventor: THRELFALL MICHAEL PAUL
IPC: G01R31/50
Filed: 2013-05-01
Abstract: A computer-implemented method for testing the integrity of electronic equipment for degradation or deterioration comprises taking a first measurement of the electrical resistance of a component and storing this value in memory or a database. A second measurement of the electrical resistance of the same or another component, which can be an identical component in an identical or other system, is taken and this value also saved. The two recorded values are compared with a difference or variance between the values calculated and if this difference exceeds a threshold, an indication is given to a user that the set limit has been breached. This method is particularly applicable to testing the continuity resistance and the insulation resistance, through measurements of the leakage current, of components of an aircraft.
